Social, legal, and ethical issues for computing technology. A gift of fire: (fourth edition) by sara baase. Updates and extras for chapter 1 of a gift of fire. By early 2015, facebook had about 1. 4 billion regular users. The first solid state memory chip (intel 3101) cost roughly 65 cents per bit in 1970. Now memory sticks cost less than 50 cents per gigabit, a billionth of the earlier price. Researchers have developed methods to store large quantities of data encoded in molecules of. Dna. (a million gigabits can potentially be stored in one cubic millimeter. ) The method still requires improvements to make it practical, and because of slow access speed, it might be better for archival storage. However, improvements in dna technology have been occurring at an extraordinarily fast pace. (hms. harvard. edu/content/writing-book-dna, aug. 2012) 3d printers continue to develop, to become cheaper and more versatile.
